ABSTRACT
Articulatory phonetics, sometimes alternatively called physiological phonetics, is a sub-branch of phonetics concerned with the study of the articulation of speech sounds. Speech sounds are produced through various interactions of speech organs acting on either an egressive (i.e. outgoing) or an ingressive (i.e. incoming) airstream. Such articulation of speech sounds is peculiar to human beings (homo loquens ‘speaking human’) and is not shared by other animals.
